I used i Marvel Universe Apocalypse for this, shaved off the moth area and sculpted on the facail parts. Shaved off all wires pads and sculpted on all the armour. Sculpted the details on afterwards. Shaved down the boots and filled in any areas that needed it. Had to drill a hole through the hand so it could hold the axe. The axe was from a WW Hulk which i sculpted the extra on to make it look more like the one used by Terrax. I even made the Rock thing. This was made using Polystyrene, Paper and glue< finished off with some flock and modelling gravel. Also some stones from my garden. lol
